Sheet 20 carries a statement of the past months balances, ton gether with whatever notations are desirloable, such as date of-payment, etc., while the sheet 21carries the daily entries vfor the account of the current month. When the current month is iinishedfthen the balance from sheet 21 is placed on sheet 2Q and sheets 21 are takenout of thebooks'and fresh A sheet 21 hasafront leaf 21 and a back leaf 2lb; vand the'upperedge 21c of the back leaf projects upwardly beyond the upper edgeof the front leaf 21a. A carbon paper is inserted between fthe -two leaves of the sheet, so ythat the entries made on the lfront,

25 leaf will be duplicated on 'the back leaf.

The projection at 21c insures that the carbon paper may be readily placed between the two leaves of the sheet without any danger of the carbon paper being placed beneath ethelower leaf 2lb. v v

Thus, when a sheet 21 is removed from the book, there are in it two copies of the current'monthly account.- These two copies may then beseparated along the fold 21d lat 3,5 the bottom ofy the sheet, 'and the two copies vfiled or used as'desiredfand according to the system o'f records pursued. For instance, one may be 'mailed to the customer and the other filed for reference.`

v The cross-sectional configuration of posts 12,- and the vcorresponding configuration of the openings in various sheets, is ofimportance, as it allo'ws ready and easy, insertion ofthe sheets, and also allows the sheets to slide"easily'on1the posts so y.that thel book maybe opened up as indicated in Fig. 1. Each post has -a'crossseetional configuration such as' illustrated in Fig. 3 and as showninl f enlarged detailI in Fig.' rll`heI two oppo- -the inner side of the post to a relatively narrow inner surface 12b. not to have. the two surfaces 12a converge com letely to a sharp edge at the inner side from being cut ,or splitat-that point, and 'to provide certainv other-'advantages here- ,inafterjexplained i-At'the outer side of the post there are two'outwardly converging etsurfaces-12c whichjmeet a broader I`outer sur'face 12?, whichouter gsurface. 12d is substantially par llel tothe inner surtaxe 12".

will be seen that the sectional configuration ofthejpost `-may be substantially',de- 6'5 scribedy as being made up of two trapezoids It is 'preferredK placed with theirbasestogether (their bases vbeing a line extending betweentthe .inter-L l section points of surfaces 12a and 12C). Now4 the aperture 30 in thev sheet` is made lof substantially the same conliguration as the cross section of the post, .the aperture being g made slightly' larger than the postso. as to lit easily around the post;, and leading from the aperture to the outer edge 20?'v of the.. sheet thereis an opening 20b wider attthe 75 outer edge of the sheet than where it1com. Y lmu-I'iicates'with theopening 30. Where this' vopening 2Ob communicates with opening 30 there are left two edges 30d which engage with the outer flat surface 12d of the post;` 80 and it is these two corner edges 30, to-v gether with' the diagonal edges 30u, that preiu 'vent 4the sheets from becoming accidentally disengaged from the post. These parts prevent/thesheets fromf being disengaged 'from 85 I the post, eveniif the book/is held upA ver. `tically .and shakenl violently; yet at the same time the sheets' may,'if desired, be removed from tliepost. The action then is -that the diagonal edge'e'surfacesy 30c engage 90:

with the diagonal'surfaces 12c of the post and spread that part of the, sheet apart and cause displacementof those parts of the ysheet adjacent edges 30d and 30ffrom a true plane. This action may be somewhat facil'itated by twisting the sheet by handout of true fiatness at the same time it is pulledl outwardly. To insert the sheet'it -is` only necessary to slide it inwardly onto the post. rlhe width of the aperture 20b atthe outer 100 edge of the sheet iswider than the surface 12c at thev ,inner side of-.the post; so thatthe two taperingedges ofthe opening 2Ob will be ut into engagement with the taper# y ing sur aces121' of the post.v lnward move- 105 ment then of course expands the aperture'.v 2()b by forcing apart its converging side edges until the edges 30d have passed the widest part of the postl Then these edges 30d and the edges 30Gy move easily into engagement 110 with the corresponding parts of the post. ln this action the parts along the converging edges of opening 20" are of course displaced (bent) from the normal plane of the sheet; but due to theobtuse'angle at 2.0c there is no 115 tendencyto turn a dog-ear at that'corner as there is in mostl loose leaf sheets which have a slot leading from the post aperture to the edge of the sheet. v

It wilt thus be seen that my construction provides a very-simple andgeffective .means of releasibly holding the sheet on the post; thesheets may be removed `from the post, l Y

, and are very easily inserted. 4 rll`his ease of l insertion adds very greatly to the eective- 125 entry sheets 20v may be removed and 're- 130` I tures 30 say two pairs of apertures, and,

either pair ma be engaged with any two posts. Now, w ile I prefer to engage each sheet with at least two posts, my design is of such accuracy that a sheet may even bev held by one post. This accuracy of holding' the sheets in alinement is due to the two opposite flat post surfaces 12b and 12l which the corresponding sheet edges-30b and 30l t fairly'snug1y,vpreventing any substantial displacement ofthe sheet.. And the breadth ofthese fiat surfaces-reduces wear on the tendency of sheets and thus-'minimizes an M the sheets to wear loose;v Furt ermore, these broad surfaces make the sheets slide easioly on the posts Without binding. Having described a'preferred invention, I claim: 1. In a device of the character. described, the combination of a' suitable back-board and a plurality of sheet-holding posts vin form of my spaced relation thereon, a. lgeneral e-ntry sheet used for and adapted to Vreceive monthly balances of a number of customers, and a plurality of current month entry sheets, smaller in size than the general entry sheets and adapted each to Areceive a current monthly account of an individual customer; such current month entry vsheets being mounted upon said posts in overlappin relation to each other and each of said s eets engaging at least 'two of said posts; each current monthly entry sheet being composed of two leaves, one superimposed upon the other, and the lowerleaf having its upper edge projecting beyond the upper-edge of the upper leaf. v V

2. In a loose leaf book, the combination of a binding post whose cross section is substantially two trapezoids placed face to. face,

and a sheet having an aperture therein spaced from its edge and an opening lead-A ing from its edge to the aperture, said o ening being wider at the edge of the s eet than where it communicates with the aperture, and said -aperture being substantially similar in formto the cross section of the post. y y v 3. In a loose leaf book, the combination of a binding postwhose cross section isp-substantially two trapezoids placed face to face, and a' sheet having an aperture therein spaced from its edge, and an opening leading from its edge to the aperture, said opening being wider at the edge ofthe edge of the sheet than where it communicates with the aperture, and said aperture being substantially similar'in form to the cross sectionof the post; the outer and inner faces of the post being substantially parallel, and

the outer face being wider than the inner' face; and the width of said opening atv the outer edge of the sheet being wider than the width of the inner face of the post, and .the width of said opening where it communicates with the aperture in the sheet being narrower than the width of the outer face of thel post.

In witness that I claim the foregoin I have hereunto subscribed my name this Ith day of August 1920.
